About this course

Computer Numerical Control (CNC) Machining is the process through which computers control machine-based processes in manufacturing. The kinds of machines controlled include lathes, mills, routers and grinders – all used for manufacturing of metal and plastic products.

In this course, you’ll learn the ins-and-outs of CNC machining; building the essential knowledge to develop and operate a project with a CNC machine.

From plan interpretation to machining and quality control, you will learn how to make the right decision in every stage of a project through videos and interactive activities.

We invite you to take part of the “Jaque Mate” company project, the objective of which is to produce chess pieces.
